SA Document Body
Security Vulnerabilities in Solaris Print Service
1. Impact
Security vulnerabilities in the Solaris print service may allow a
remote unprivileged user the ability to run arbitrary code as root or
cause a Denial of Service (DoS) condition.
2. Contributing Factors
These issues can occur in the following releases:
SPARC Platform
* Solaris 8 without patch 109320-20
* Solaris 9 without patch 113329-19
* Solaris 10 without patch 127127-11
x86 Platform
* Solaris 8 without patch 109321-20
* Solaris 9 without patch 114980-20
* Solaris 10 without patch 127128-11
3. Symptoms
If the issue described in BugID 6599950 occurs, users may experience a
DoS condition on the Solaris print system.
There are no predictable symptoms that would indicate the described
issue has been exploited to execute arbitrary code.
4. Workaround
To work around the described issues, do the following:
For Solaris 8 and Solaris 9 Systems:
Disable the BSD print protocol adaptor (in.lpd(1M)) by doing the
following:
1. Edit the "/etc/inetd.conf" file and comment out the following line
by adding the "#" symbol to the beginning of the line as shown:
#printer stream tcp6 nowait root /usr/lib/print/in.lpd in.lpd
2. Tell the inetd(1M) process to reread the newly modified
"/etc/inetd.conf" file by sending it a hangup signal, SIGHUP:
# /usr/bin/pkill -HUP inetd
For Solaris 10 Systems:
Disable the main print services by executing the following commands:
# svcadm disable svc:/application/print/rfc1179
# svcadm disable svc:/application/print/ipp-listener
# svcadm disable svc:/application/print/print/server
5. Resolution
These issues are addressed in the following releases:
SPARC Platform
* Solaris 8 with patch 109320-20 or later
* Solaris 9 with patch 113329-19 or later
* Solaris 10 with patch 127127-11 or later
x86 Platform
* Solaris 8 with patch 109321-20 or later
* Solaris 9 with patch 114980-20 or later
* Solaris 10 with patch 127128-11 or later
